no data after flashing rom

I have tried flashing my friends rom on lg 2x its the Cincinnati bell version. I tried 3 different roms so far and the data don't work anymore. after that I even flashed to stock with nvflash and data still don't work, omg what the hell did I do. I always do full wipe. can you help me

I assume you made sure the mobile data is on (settings-data usage-mobile data).
Did the flashing change the baseband? If so, consult the following excellent thread:

Your company can provide your APN settings, just call them. Or go to APN and copy them to a piece of paper.

>> Change sim .
Suggest you manually add your networks APN settings and read the faqs and guides before flashing anything .

why not just writing down your apn on paper? It will take 2 minutes

no cellular network

Hi there:
I had a rooted nexus 6 with Android 6.
I was playing with chmod and root and messed up some system permissions.
I have re-installed several Nexus 6 Google images 5.1 6.0 etc...
I have everything except cellular signal. It says no service and sometimes no sim card.
I have taken my sim and put it in another phone and it worked.
When I go to *#*#4636#*#*
It says GSM: emergency service only and GPRS service: disconnected.
I tried to change the network type to GSM only and others with no success.
Any help to further diagnose this would be appreciated..
Thanks

Very good point.
When I flashed 6.0.1
under cellular network settings , I only see Data raoming, Preferred network type and System select.
no APN settings
When I re-flashed 5.0.1 , I could see the apn settings, but when I go to it, it says something like that the user doesn't have permission to view the settings. I even tried to add a new settings and save it, but the message stayed there and I see no APN list at all..
I might have messed up the APN permissions with chmod, but I would think a system re-flash would have corrected it..
Thanks

Does your IMEI match the number on your SIM card tray?
